Update Sentinel protocol: The Sentinel protocol is now supported by autodetection. Added Autodetection indicator: In the previous version no indicator showed that an auto detection is running. A new pseudo sensor type has been introduced which now causes the auto detection string to be displayed while the detection is running in the background.
